| 中文摘要: |
| 将线性蠕变的控制方程做摄动展开，用加权余量法和二类变量的变分原理，引入有限元线和Ｈａｍｉｌｔｏｎ混合状态元技术，建立了两种求解缄性蠕变问题的摄动增解析计算格式。 |
| 英文摘要: |
| Governing equations for the problem of linear
creep are perturbationally expanded, and both finite element method of line and the method of
mixed state Hamilton element are introduced using weighting technique and 2 type variable based
variational principle, two kinds of perturbational semi analytical computational formulae are
therefore established to solve the linear creep problems. |
